1 Why should we save energy? Americans now spend over $700 billion on energy Americans now spend over $700 billion on energy Energy demand is expected to climb 40% by 2025 Energy demand is expected to climb 40% by 2025 85% of US Carbon Emissions stem from electricity generation and use. 85% of US Carbon Emissions stem from electricity generation and use. Greenhouse gas emissions are expected to climb as much as 60% by 2025 Greenhouse gas emissions are expected to climb as much as 60% by 2025

2 So What can we do?

3 Use your Blinds On cold days, turn window blinds downward. On cold days, turn window blinds downward. Use the winter sun for both lighting and heating. Use the winter sun for both lighting and heating. On cold nights, turn blinds upward before you leave. On cold nights, turn blinds upward before you leave. Cold air will be trapped next to the window and warm air will remain in the room. Cold air will be trapped next to the window and warm air will remain in the room.

4 Lighting According to the United States Environmental Protection Agency (EPA), 25 to 30 percent of a building’s energy use goes toward building lighting.

5 It all adds up! A typical school classroom has 14-2 lamp light fixtures. If the lights in this classroom are left on for an extra 2 hour per day; the added cost is approximately $18.00 per year. High School average 60 classrooms= $1,080.00 per year District Wide: Over $15,000 of added cost or potential savings

6 Why CFL’s? CFLs use 66% less energy than a standard incandescent bulb Last up to 10 times longer. Replacing a 100-watt incandescent with a 32-watt CFL can save you at least $30 in energy costs over the life of the bulb. If every household in the U.S. replaced one light bulb with an ENERGY STAR qualified compact fluorescent light bulb (CFL), it would prevent enough pollution to equal removing one million cars from the road.

7 Heating your home For each degree you lower the temperature in your home or at work, you can cut your winter heating bills by 4%,depending on how many hours a day you turn down the heat. For each degree you lower the temperature in your home or at work, you can cut your winter heating bills by 4%,depending on how many hours a day you turn down the heat. An ENERGY STAR programmable thermostat can make this easy. An ENERGY STAR programmable thermostat can make this easy.

8 Energy Vampires In the U.S. alone, the amount of energy consumed by home electronics when not in use equals the annual output of SIX power plants. In the U.S. alone, the amount of energy consumed by home electronics when not in use equals the annual output of SIX power plants.

9 Turn off your computer Even screen savers that make the screen go blank don’t significantly lower energy use. Even screen savers that make the screen go blank don’t significantly lower energy use. The best way to save your screen and save energy at the same time is to turn off your computer when you are not using it. The best way to save your screen and save energy at the same time is to turn off your computer when you are not using it. If you will be away for 30 minutes or more, turn everything off –the monitor and the CPU. If you will be away for 30 minutes or more, turn everything off –the monitor and the CPU.

10 If you will be away for 15 minutes or more: turn off your monitor (while leaving the CPU on) If you will be away for 15 minutes or more: turn off your monitor (while leaving the CPU on) Your monitor uses the most energy, switching if off when not in use will cut your energy use. Your monitor uses the most energy, switching if off when not in use will cut your energy use. The CPU will continue to use energy but this is a good compromise. The CPU will continue to use energy but this is a good compromise. Turning off a computer monitor @ night and on weekends can save more than $50.00 per year. Turning off a computer monitor @ night and on weekends can save more than $50.00 per year.

11 Summary Turn off monitor between uses. Turn off monitor between uses. Use compact fluorescent bulbs in lamps. Use compact fluorescent bulbs in lamps. Use natural lighting from windows to replace or supplement electric lighting. Use natural lighting from windows to replace or supplement electric lighting. Be on alert for machines or equipment that shouldn’t be left running. Be on alert for machines or equipment that shouldn’t be left running.
